Beyond the controversy: Instructional scaffolds to promote critical evaluation and understanding of Earth science
Resource
Our project team has been developing and testing four MELs about socio-scientific issues (climate change, wetlands and land use, fracking and earthquakes) and abstract ideas (formation of Earth’s Moon) for use in high…
Resource
By evaluating alternative models, students can improve upon their scientific literacy and understanding of scientific practices. Suggestions from classroom use of the Moon MEL will help teachers use this activity in a…
